我正在使用Ubuntu18.04.1Nginx1.14.0和HTTP2和PHP7.2.7设置一个新服务器，这是我尝试设置的第一个同时启用了IPv4和IPv6的服务器。一切都很好，直到我测试了一个有很多缺失图像的页面。服务器似乎永远都要花很长时间才能意识到它们丢失并对http请求作出响应。某些丢失的文件显示HTTP状态为"502 bad gateway“。是DNS问题导致了这些延迟和502错误吗?我应该在设置中更改什么？

编辑:这里可能有很多不必要的信息，但由于还不清楚服务器反应太慢的原因，其中一些可能很重要。

php脚本应该不是问题，我的旧服务器，使用完全相同的页面，加载非常快。

区域文件同时包含IPv4和IPv6的记录。

编辑:下面的整个DNS理论可能不是原因，请参阅：Why does this nginx server redirect to a wrong domain?。服务器重定向到错误的域。当强制nginx服务器只侦听IPv4并浏览到server1.eu时，SSL证书不匹配(仅对server2.eu有效)，在强制接受证书后，有一个301重定向到server2.eu现在，当我从启用站点的服务器中删除服务器"server2.eu“并重新加载nginx时，SSL证书不匹配和重定向没有发生。当服务器"server2.eu“从站点启用中删除，并且在nginx服务器设置中禁用server1.eu服务器IPv4时，它会导致在浏览到服务器1.eu时”没有连接到服务器“，而服务器"server2.eu”从站点启用中删除，并且server1.eu服务器IPv6从nginx服务器设置中禁用，这会导致服务器变慢。然后我再次恢复server2.eu服务器，并从nginx服务器设置中禁用server1.eu服务器IPv4，结果: SSL证书不匹配(仅对server2.eu有效)，在强制接受证书301重定向到server2.eu之后，从nginx服务器设置中禁用server1.eu服务器IPv6会导致快速服务器，“慢服务器”问题得到解决，因此server1.eu依赖于错误的服务器才能正常工作。同时，IPv6地址2a03:b0c0:0:1010::190:6001仍然重定向到server1.eu

编辑:服务器的一个不同之处在于旧的http1.1和新的http2。禁用http2可以解决超长加载和502错误。页面的加载时间仍然比旧服务器长(6.40比3.18秒)

当增加/etc/php/7.2/fpm/pool.d/www.conf中的设置时，错误消失，加载时间仍然很长: 8,4秒对3,16秒，但更接近旧服务器：

代码语言：javascript
复制
pm.max_children = 100
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 30

旧的服务器只支持IPv4，HTTP1.1，空闲内存较少，PHP5.5.9-1Ubuntu 14.04.5LTS和Nginx 1.4.6。它的设置是：

代码语言：javascript
复制
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

这个问题有如此多的内容，甚至不清楚被问到了什么-所有这些非服务器日志404错误对大多数读者来说意义不大，当然，我从来没有听说过IPv6的存在会对突然返回404错误的图像请求产生任何影响。

您已经提供了find /etc/nginx/{conf.d,sites-enabled}和find /etc/nginx/{conf.d,sites-enabled} | xargs fgrep listen，并且没有什么不寻常之处--似乎每个非IPV4 listen都伴随着一个IPv6 listen。http://nginx.org/r/listen。

下一步，IMHO，将只使用curl直接重现错误，包括使用-v、-4和-6标志的某种组合来查看发生了什么。绝对确保您是在同一客户端主机上执行此操作，而您实际上遇到了您正在尝试更正的错误；整个问题也可能源于客户端的某些错误。

curl的另一个有用特性是，如果您认为您的问题与DNS相关，则可以使用域映射。如果您将-v选项与curl一起使用，您已经可以看到请求将转到哪个IP地址(这可能很容易揭示过时的DNS，除非它只是在您的浏览器中陈旧)；下一步是可能使用--resolve选项覆盖IP地址，例如--resolve test.vuyk.eu:443:2a03:b0c0:0:1010::190:6001或类似的选项。

最后，如果您仍然仅通过IPv6 (-6)而不是通过IPv4 (-4)遇到延迟和故障，那么问题可能与客户端上的IPv6连接有关；具体地说，如果您的连接通过隧道或第6个通道，则可能MTU发现在路径上中断；在Linux上，您可以尝试使用tracepath进行故障排除，它将沿路径输出pmtu值。

顺便说一句，我试过通过TMo US的IPv6本地连接访问您的站点，IPv6的MTU值为1500 (他们实际上通过IPv6隧道IPv4，所以据我所知，T-Mo US上的IPv4 MTU值为1472 )，我看不到任何明显的问题(据我所知，您目前确实有为test.vuyk.eu发布的IPv6记录)。也许整个问题都是由于您的设置中客户端的DNS缓存陈旧造成的？对于客户端中看到的所有404错误，您在服务器日志中看到的是什么？！
